HELP PLZ i need help with this math side i just need b,c,d a =4x+2y=16

tino4ka555 [31]

Answer:

Please check the explanatio.

Step-by-step explanation:

Solving Part b)

We know that the slope-intercept form of the equation line is

$y=mx+b$

where m is the slope and b is the y-intercept

Given the equation

$4x+2y=16$

Re-writing the equation in the slope-intercept form

$4x+2y=16$

$y=-2x+8$

Here, m=-2 and b=8

Thus, the equation in the slope-intercept form will be:

$y=-2x+8$

Solving Part c)

As you sold two pounds of cheddar cheese.

i.e. y=2

substituting y=2 in the slope-intercept form of the line equation

$y=-2x+8$

$2=-2x+8$

Subtract 8 from both sides

$-2x+8-8=2-8$

$-2x=-6$

Divide both sides by -2

$\frac{-2x}{-2}=\frac{-6}{-2}$

$x=3$

You sold 3 pounds of swiss cheese.

Solving Part d)

$y=-2x+8$

putting x=2.5 in the equation

$y=-2x+8$

$2=-2\left(2.5\right)+8$

$2=3$

The sides are not equal

FALSE

Thus, x=2.5 does not make any sense in the context of the problem.

I do not get this question

inna [77]

35%

Explanation:

The overall percentage must add up to 100%

Because of this...

100% (total) - 49% (swimming) = 51%

51% - 16% (biking) = 35% (rollerblading)

Which binomial is a factor of 49x2 + 84 xy + 36y2?

skad [1K]

Answer:

(7x+6y) is a binomial factor of the given expression $49x^2+84xy+36y^2$

Therefore $49x^2+84xy+36y^2=(7x+6y)(7x+6y)$

Step-by-step explanation:

Given expression is $49x^2+84xy+36y^2$

To find the binomial factor :

$49x^2+84xy+36y^2$

Rewritting the above expression as

$=7^2x^2+2(7)(6)xy+6^2y^2$

$=(7x)^2+2(7x)(6y)+(6y)^2$

$=(7x+6y)^2$ ( using the formula $=(a+b)^2=a^2+2ab+b^2$ here a=7x and y=6y )

$=(7x+6y)(7x+6y)$ ( using the formula $=(a+b)^2=(a+b)(a+b)$ )

Therefore $49x^2+84xy+36y^2=(7x+6y)(7x+6y)$

(7x+6y) is a binomial factor of the given expression $49x^2+84xy+36y^2$

Solve by graphing: use any method x + y = 6 x - y = 4

jekas [21]

X+y=6
x-y=4
using these equations we solve for either x or y in one and plug it into that variable in the other equation.
x=y+4 so y+4+y=6 so 2y=2 so y=1
now using y=1 put into first equation. x+1=6 so x=5
so we know our graph goes through the coordinate point (5,1) then just make an x table and use some values to find the corresponding y coordinate and then do that for at least three points or more if needed to find the best fit for graph. Hope this helps walk you through it! Any questions please just ask! Thank you!
